The Hope Probe makes new scientific observations at the north pole of Mars

v + T – normal size

The Information Center platform for the Emirates Mars Exploration Project, “Probe of Hope”, published a recent image of the red planet carrying new scientific observations, as the EXI digital exploration camera dedicated to taking high-resolution color images of Mars on July 4, 2022, from an altitude of 39,800 km, detected that it In late fall and during the northern hemisphere winter of the planet, at 259° solar longitude, the Arctic region is obscured by thick clouds of water ice called the Arctic mantle.

Scientific explanations

Through these images, it was noted that there are bright and dark lines in the Arctic cover, while one of the explanations for this phenomenon appears, that the regional winds interact with the high terrain of the huge shield volcano “Alba Patera” south of the Arctic cover, which leads to the emergence of atmospheric waves, and they become These waves are visible as alternating bright and dark patterns in the arctic clouds, while the image shows the Valles Mariners valley group, which is partially obscured by a haze of dust below the center of the image.

And the “Probe of Hope” continues its primary mission successfully by mapping the atmosphere of Mars, as it is close to completing a Martian year “two Earth years”, in studying the atmosphere of the Red Planet, while since its arrival in the orbit of Mars on the ninth of February 2021, the Hope Probe has managed By providing many and varied information about the Martian atmosphere, within 5 batches of high-quality data and images, where new discoveries of climate phenomena were monitored, and this scientific data also gained the attention of the global scientific community, due to the importance and modernity of this information, and by using it a shift will be made. Quality in the global science and space sector.

first package

The first package of data included unique images of Mars that capture unprecedented observations about the behavior of the red planet’s atmospheric gases and the interactions that occur between them. The observations showed significant differences in the abundance of both atomic oxygen and carbon monoxide in the upper atmosphere of Mars on the day side of the planet.

The new discoveries provided by the first package of data contribute to changing scientists’ previous concepts about the distribution of ultraviolet light emitted from the upper atmosphere of Mars, as they show the presence of vast structures of atomic oxygen abundance that differ in levels from expected, while also indicating unusual atmospheric disturbances in the atmosphere. Atmospheric, especially since the pictures were taken at a time when Mars was close to the top of its orbit (the farthest from the sun), while the solar activity was low, as the pictures showed the exceptional scene of oxygen emissions at a wavelength of 130.4 nanometers.

105 GB

The second package revealed important information that helps the global scientific community to develop more accurate scientific models of the Martian atmosphere, and contributes to a deeper understanding of its changes. Scientific study about the red planet, specifically from May 23 to August 31, 2021.

In early April, the Emirates Mars Exploration Project published the third package of data, amounting to 29 gigabytes, collected by the probe between September 1 and November 30, 2021, which helped experts and scientists expand their understanding of climate change on the Red Planet, especially since the digital exploration camera detected Nine photos on November 22, 2021, each taken with a time difference of five minutes from the previous one, and these photos focus on studying the movement of winds, observing the phenomenon of cloud formation, and the movement of dust storms.

Notes

The fourth package of data provided a new set of scientific observations related to the atmosphere of Mars, most notably the observations monitored by the ultraviolet spectrometer of the Hope Probe, which provides better coverage of the twilight of Mars, and the ultraviolet spectrometer monitored particles of solar energy and galactic cosmic rays. Through an experiment he conducted by observing what the device captures when it is closed, and the scale also showed the possibility of working with higher sensitivity and accuracy if needed when capturing scientific observations.

The Emirates Mars Exploration Project provided the fifth package of 236.8 gigabytes of images and data with a size of 236.8 gigabytes, which covered the period between March 1 and May 31, 2022, and included specialized scientific observations to study the movement of dust that was monitored by the Digital Exploration Camera, and new observations monitored by the scale. Ultraviolet spectrophotometry of the Red Planet’s upper atmosphere, conducted about once a week, is a high-resolution stare in wavelength terms of the Martian disk.

The EXI digital exploration camera of the probe was able to take special high-resolution images, as the camera, which was specially designed to capture movements and changes in the atmosphere, monitored the movement of dust on January 9, 29 and February 23 of this year, and it also monitored clouds on December 42. 2021, January 7 and 25 of the current year 2022.

scientific community

The scientific mission of the Emirates Mars Exploration Project, the “Probe of Hope”, focuses on collecting data and monitoring observations that help study the relationship between the upper and lower layers of the Martian atmosphere, which allows the scientific community to form a comprehensive picture of the Martian climate and atmosphere at different times of the day and throughout the seasons of the year. Martian.

The “Probe of Hope” carries three innovative scientific devices: the EXI Digital Exploration Camera, which takes high-resolution color images of Mars, and is also used to measure ice and ozone in the lower atmosphere, and the EMIRS infrared spectrometer, which measures temperatures and the distribution of dust, water vapor and clouds. icy troposphere, and EMUS ultraviolet spectrometer, measures oxygen and carbon monoxide in the Martian thermosphere and hydrogen and oxygen in the Martian exosphere.
